To aZZ whom i may concern:

Be it known that we, ERICE Cromo SAMPsoN and GUSTAF JOHNSON, citizens of the United States, residing at Jamestown,

5 in the county of Chautauqua and State oi? New York, have invented certain new and useful improvements in Suspension Devices for Drawers, of which the following is a specification.

lo This invention is a suspension device for etc., and

the drawers of cabinets, file cases, is an improvement upon Patent No. 884,476, April 14, 1968, to E. A. Ekedalil and E. G. Sampson. l5 The prior device, as well as the present device, includes loose or floating anti-friction rollers, and it is an important obje-ct oi the present invention to prevent certain of such rollers from becoming displaced il@ 'from tire device during sransportation an handling, and to accomplish tlriisresultwitliout interfering in any manner whatsoever with the Jfree rotation of said rollers.

A further object of tlie invention is to 53e provide an improved dog arrangement wl'iereb,7 outward movement of the drawer upon the suspension device is limited, and .also whereby the drawer may be released 'from tire suspension ievice in order it 3@ may be entirely removed therefrom. ln this connection, it is also proposed to arrange fior the convenient re-assemblage oi tbe drawer with tbe suspension device.

With iliese and other oloiectsA in view, tlie 35 present invention consists in the combination and arrangement of parts, as will be Vv described, sliown in hereinafter mor ugs, and ifortla in appended clair-ns. being understood s oceans 1 ne el n@ .re advan- Fig. 3 is an enlarged cross-sectional view taken on the line 3-3 of Fig.

Fig. l is a detail perspective view ci the upper guideway member.

Fig. 5 is an enlarged detail elevation looking at the reverse side or the suspension member.

Fig. 6 is a longitudinal sectional view of Fig. 5, the suspension member being in the 60 position shown in Figs. l and 2 of the drawings. l

Fig. 7 is a detail perspective view oi the drawer rail member.

Fig. 8 is a detail perspective view of tbe 65 lower guideway member.

Like characters of reference designate corresponding parts on each of the figures of the drawings.

'"llie present device includes a guideway 7 made up of an upper stationary member A and a lower stationary member E, eacli oi the members being suitably connected to an upright or side wall C ci a cabinet, iile case or the like. 75

The lower guide member E is in 'die forro. of a channel bar, as best illustrated in Figs.

3 and 8 of tbe drawings. 'lliis channel has a substantiallv horizontal bottoni l which is of iiuil widtlL throughout its length e@ and extends throughout the length oif the entire bar and is provided at its inner edge with a depending flange 2; leaving suieable openings 3 lfor tlie reception oi fastening devices, suoli as sliown at Ll, in l, 2 E of the drawings, whereby tbe guidewav member may be secured to 'l e wall C with lle open side oiE tine channel ear toward cl `sed bjr tbe upright ni t elianneT bar is less i felt or the like l1, constituting a stop and a noise-deadening device, as will hereinafter appear. At suitable intervals, studs or pins 12 and 13 project from the upright wall of the channel bar toward the open side thereof, said studs being immediately beneath the top portion 5 of the bar.

The guideway member A is secured to the upright or side wall C a suitable distance above the front portion of the guideway member B, the upright wall of the member A being perforated, as at 14, to receive fastenings for seeming the member to the upright C. The member A is in the fo'rm of an angle bar having a longitudinal dependingflange 15 along the outer edge of the bottom of the bar, the upright wall of the bar, at its rear end,being bent across the bar, as at 16, to form a stop, aswill be hereinafter explained.

The suspension member of the device is designated D, and is in the form of a channel bar, the bottom of which is provided on the open side of the bar with an upstanding flange 17 extending throughout the entire length of the bar, andthis flange is provided throughout its length with an internal chan nel 18 formed by striking up a hollow rib in the flange 17. Ait suitable intervals punch pricks 19, 2O and 2l, are formed in the lower edge portion of the channel 18 so as to punch metal into the channel and force said metal into blocks of leather, felt or the like 22 23 and 24, which latter constitute sound-deadening stops :for anti-friction rollers 25, 2G and 27. Each of these rollers is provided with an axially-disposed conical stud or projection 29 which .is received within the channely i8, whereby said anti-friction rollers are prevented from becoming accidentally displaced upwardly through the open top of the channel bar suspension member. The top 30 of the suspension member terminates short of the front of the member in an upwardly and forwardly inclined lip 3l, and in front of this lip, the upright wall of the member is extended, as at 32, and supports a dog 33 which is pivoted between its ends, as at 34, upon the extension 32. IThis dog is substantially triangular in shape and is provided with a-depending shoulder 35 immediately in front of the lip 3l, from which shoulder the lower edge of the dog is beveled or inclined upwardly and forwardly, as at 36. The dog isr extended in rear ci the shoulder 35 at the top thereof, as at 37, to form a weight overbalancing the forward end portion of the dog and normally holding the same in a substantially horizontal position with the weight portion 37 engaging the lip 31as a stop. At the rear of the suspension member D and on the closed side thereof, there is attached a plate 38 which projects below the member and is provided with a bottom substantially horizontal dange `suspension member.

projects above the top of the member and constitutes a stop to engage the stop liange 16 on the upper guideway member A and thereby limit the forward movement of the Working within the suspension member is a drawer rail E, shown in detail in Fig. 7 of the drawings. This drawer rail is in the form lof a Z-bar, the bottom edge of its` lower flange 45 resting upon the anti-friction rollers 25, 26 and 27, while its upper flange member 46 is provided with suitable perforations 47 for the reception of fastenings whereby the rail may be secured to the adjacent side of a drawer. This drawer rail y is adapted to .be slipped endwise into the suspension member through the open front thereof and beneath the dog, the inner end of the rail being provided with a bearing member 48 underlying the to flange of the suspension member and suita ly secured to the rail and lying on top of the horizontal body portion thereof.. Tlhis bearing has a rounded or beveled rear extremity to engage the beveled edge 36 of the dog and move the latter upwardly when the rail is pushed into the suspension member, while the forward portion of the bearing is also beveled or inclined so as to wipe across the lower edge of the shoulder 35 of the dog and lift the same to permit withdrawal of the rail. Accidental or unintentional removal of the rail is prevented by a stop 49 provided upon the rail a short distance in front of the bearing 48, said stop being adapted to engage against the rear face of the vshoulder 35 on the dog and thereby prevent accidental displacement ot the rail. By pressing downwardly upon the forwardy free end of the dog, the latter may be tilted into the inclined position shown in Fig. 2, whereupon the rail is .free to be removed. The normal. position of the dog is shown in full lines, and is maintained in this position by the weighted rear terminal 37 of the dog. The

stop 49 is preferably a block of leather, felt ges er relief eeiiefisu'ed by 'the Ldewey meiiibef B mici 'the Yieiibei :Lf-'seembie Se as ier infie ehe eimime of me lower iengged. s iseenslen D.
